What are the differential current protection methods for relay protection
The differential protection scheme utilizes current transformers (CTs) placed at both ends of the protected zone to measure the incoming and outgoing currents. These CTs feed the measured current values to a differential relay. In each case, the measurement is based on Kirchhoff's laws which state that the geometric (vector) sum of the. What controls it: CT location, CT polarity, CT ratio, transformer compensation, restraint logic, and relay settings control performance.
